## ✨ Features

- 📦 Manage all your Neovim plugins with a powerful UI
- 🚀 Fast startup times thanks to automatic caching and bytecode compilation of Lua modules
- 💾 Partial clones instead of shallow clones
- 🔌 Automatic lazy-loading of Lua modules and lazy-loading on events, commands, filetypes, and key mappings
- ⏳ Automatically install missing plugins before starting up Neovim, allowing you to start using it right away
- 💪 Async execution for improved performance
- 🛠️ No need to manually compile plugins
- 🧪 Correct sequencing of dependencies
- 📁 Configurable in multiple files
- 📚 Generates helptags of the headings in `README.md` files for plugins that don't have vimdocs
- 💻 Dev options and patterns for using local plugins
- 📊 Profiling tools to optimize performance
- 🔒 Lockfile `lazy-lock.json` to keep track of installed plugins
- 🔎 Automatically check for updates
- 📋 Commit, branch, tag, version, and full [Semver](https://devhints.io/semver) support
- 📈 Statusline component to see the number of pending updates
- 🎨 Automatically lazy-loads colorschemes

## ⚡️ Requirements

- Neovim >= **0.8.0** (needs to be built with **LuaJIT**)
- Git >= **2.19.0** (for partial clones support)
- a [Nerd Font](https://www.nerdfonts.com/) **_(optional)_**

## 📦 Installation

You can add the following Lua code to your `init.lua` to bootstrap **lazy.nvim**:

<!-- bootstrap:start -->

```lua
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "https://github.com/folke/lazy.nvim.git",
    "--branch=stable", -- latest stable release
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)
```

<!-- bootstrap:end -->

Next step is to add **lazy.nvim** below the code added in the prior step in `init.lua`:

```lua
require("lazy").setup(plugins, opts)
```

- **plugins**: this should be a `table` or a `string`
  - `table`: a list with your [Plugin Spec](#-plugin-spec)
  - `string`: a Lua module name that contains your [Plugin Spec](#-plugin-spec). See [Structuring Your Plugins](#-structuring-your-plugins)
- **opts**: see [Configuration](#%EF%B8%8F-configuration) **_(optional)_**

```lua
-- Example using a list of specs with the default options
vim.g.mapleader = " " -- Make sure to set `mapleader` before lazy so your mappings are correct

require("lazy").setup({
  "folke/which-key.nvim",
  { "folke/neoconf.nvim", cmd = "Neoconf" },
  "folke/neodev.nvim",
})
```

ℹ️ It is recommended to run `:checkhealth lazy` after installation.

### Lazy Loading

**lazy.nvim** automagically lazy-loads Lua modules, so it is not needed to
specify `module=...` everywhere in your plugin specification. This means that if
you have a plugin `A` that is lazy-loaded and a plugin `B` that requires a
module of plugin `A`, then plugin `A` will be loaded on demand as expected.

If you don't want this behavior for a certain plugin, you can specify that with `module=false`.
You can then manually load the plugin with `:Lazy load foobar.nvim`.

You can configure **lazy.nvim** to lazy-load all plugins by default with `config.defaults.lazy = true`.

Additionally, you can also lazy-load on **events**, **commands**,
**file types** and **key mappings**.

Plugins will be lazy-loaded when one of the following is `true`:

- The plugin only exists as a dependency in your spec
- It has an `event`, `cmd`, `ft` or `keys` key
- `config.defaults.lazy == true`

#### 🌈 Colorschemes

Colorscheme plugins can be configured with `lazy=true`. The plugin will automagically load
when doing `colorscheme foobar`.

> **NOTE:** since **start** plugins can possibly change existing highlight groups,
> it's important to make sure that your main **colorscheme** is loaded first.
> To ensure this you can use the `priority=1000` field. **_(see the examples)_**

#### ⌨️ Lazy Key Mappings

The `keys` property can be a `string` or `string[]` for simple normal-mode mappings, or it
can be a `LazyKeys` table with the following key-value pairs:

- **[1]**: (`string`) lhs **_(required)_**
- **[2]**: (`string|fun()`) rhs **_(optional)_**
- **mode**: (`string|string[]`) mode **_(optional, defaults to `"n"`)_**
- **ft**: (`string|string[]`) `filetype` for buffer-local keymaps **_(optional)_**
- any other option valid for `vim.keymap.set`

Key mappings will load the plugin the first time they get executed.

When `[2]` is `nil`, then the real mapping has to be created by the `config()` function.

```lua
-- Example for neo-tree.nvim
{
  "nvim-neo-tree/neo-tree.nvim",
    keys = {
      { "<leader>ft", "<cmd>Neotree toggle<cr>", desc = "NeoTree" },
    },
    config = function()
      require("neo-tree").setup()
    end,
}
```

### Versioning

If you want to install a specific revision of a plugin, you can use `commit`,
`tag`, `branch`, `version`.

The `version` property supports [Semver](https://semver.org/) ranges.

<details>
<summary>Click to see some examples</summary>

- `*`: latest stable version (this excludes pre-release versions)
- `1.2.x`: any version that starts with `1.2`, such as `1.2.0`, `1.2.3`, etc.
- `^1.2.3`: any version that is compatible with `1.2.3`, such as `1.3.0`, `1.4.5`, etc., but not `2.0.0`.
- `~1.2.3`: any version that is compatible with `1.2.3`, such as `1.2.4`, `1.2.5`, but not `1.3.0`.
- `>1.2.3`: any version that is greater than `1.2.3`, such as `1.3.0`, `1.4.5`, etc.
- `>=1.2.3`: any version that is greater than or equal to `1.2.3`, such as `1.2.3`, `1.3.0`, `1.4.5`, etc.
- `<1.2.3`: any version that is less than `1.2.3`, such as `1.1.0`, `1.0.5`, etc.
- `<=1.2.3`: any version that is less than or equal to `1.2.3`, such as `1.2.3`, `1.1.0`, `1.0.5`, etc

</details>

You can set `config.defaults.version = "*"` to install the latest stable
version of plugins that support Semver.

## 🚀 Usage

Plugins are managed with the `:Lazy` command.
Open the help with `<?>` to see all the key mappings.

You can press `<CR>` on a plugin to show its details. Most properties
can be hovered with `<K>` to open links, help files, readmes,
git commits and git issues.

Lazy can automatically check for updates in the background. This feature
can be enabled with `config.checker.enabled = true`.

Any operation can be started from the UI, with a sub command or an API function:

<!-- commands:end -->

Any command can have a **bang** to make the command wait till it finished. For example,
if you want to sync lazy from the cmdline, you can use:

```shell
$ nvim --headless "+Lazy! sync" +qa
```

`opts` is a table with the following key-values:

- **wait**: when true, then the call will wait till the operation completed
- **show**: when false, the UI will not be shown
- **plugins**: a list of plugin names to run the operation on
- **concurrency**: limit the `number` of concurrently running tasks

Stats API (`require("lazy").stats()`):

<!-- stats:start -->

```lua
{
  -- startuptime in milliseconds till UIEnter
  startuptime = 0,
  -- when true, startuptime is the accurate cputime for the Neovim process. (Linux & Macos)
  -- this is more accurate than `nvim --startuptime`, and as such will be slightly higher
  -- when false, startuptime is calculated based on a delta with a timestamp when lazy started.
  real_cputime = false,
  count = 0, -- total number of plugins
  loaded = 0, -- number of loaded plugins
  ---@type table<string, number>
  times = {},
}
```

<!-- stats:end -->

**lazy.nvim** provides a statusline component that you can use to show the number of pending updates.
Make sure to enable `config.checker.enabled = true` to make this work.

<details>
<summary>Example of configuring <a href="https://github.com/nvim-lualine/lualine.nvim">lualine.nvim</a></summary>

```lua
require("lualine").setup({
  sections = {
    lualine_x = {
      {
        require("lazy.status").updates,
        cond = require("lazy.status").has_updates,
        color = { fg = "#ff9e64" },
      },
    },
  },
})

```

### 📆 User Events

The following user events will be triggered:

- **LazyDone**: when lazy has finished starting up and loaded your config
- **LazySync**: after running sync
- **LazyInstall**: after an install
- **LazyUpdate**: after an update
- **LazyClean**: after a clean
- **LazyCheck**: after checking for updates
- **LazyLog**: after running log
- **LazyLoad**: after loading a plugin. The `data` attribute will contain the plugin name.
- **LazySyncPre**: before running sync
- **LazyInstallPre**: before an install
- **LazyUpdatePre**: before an update
- **LazyCleanPre**: before a clean
- **LazyCheckPre**: before checking for updates
- **LazyLogPre**: before running log
- **LazyReload**: triggered by change detection after reloading plugin specs
- **VeryLazy**: triggered after `LazyDone` and processing `VimEnter` auto commands
- **LazyVimStarted**: triggered after `UIEnter` when `require("lazy").stats().startuptime` has been calculated.
  Useful to update the startuptime on your dashboard.

## 🔒 Lockfile `lazy-lock.json`

After every **update**, the local lockfile is updated with the installed revisions.
It is recommended to have this file under version control.

If you use your Neovim config on multiple machines, using the lockfile, you can
ensure that the same version of every plugin is installed.

If you are on another machine, you can do `:Lazy restore`, to update all your plugins to
the version from the lockfile.

## ⚡ Performance

Great care has been taken to make the startup code (`lazy.core`) as efficient as possible.
During startup, all Lua files used before `VimEnter` or `BufReadPre` are byte-compiled and cached,
similar to what [impatient.nvim](https://github.com/lewis6991/impatient.nvim) does.

My config for example loads in about `11ms` with `93` plugins. I do a lot of lazy-loading though :)

**lazy.nvim** comes with an advanced profiler `:Lazy profile` to help you improve performance.
The profiling view shows you why and how long it took to load your plugins.

## 🐛 Debug

See an overview of active lazy-loading handlers and what's in the module cache.

## ▶️ Startup Sequence

**lazy.nvim** does **NOT** use Neovim packages and even disables plugin loading
completely (`vim.go.loadplugins = false`). It takes over the complete
startup sequence for more flexibility and better performance.

In practice this means that step 10 of [Neovim Initialization](https://neovim.io/doc/user/starting.html#initialization) is done by Lazy:

1. All the plugins' `init()` functions are executed
2. All plugins with `lazy=false` are loaded. This includes sourcing `/plugin` and `/ftdetect` files. (`/after` will not be sourced yet)
3. All files from `/plugin` and `/ftdetect` directories in you rtp are sourced (excluding `/after`)
4. All `/after/plugin` files are sourced (this includes `/after` from plugins)

Files from runtime directories are always sourced in alphabetical order.

## 📂 Structuring Your Plugins

Some users may want to split their plugin specs in multiple files.
Instead of passing a spec table to `setup()`, you can use a Lua module.
The specs from the **module** and any top-level **sub-modules** will be merged together in the final spec,
so it is not needed to add `require` calls in your main plugin file to the other files.

The benefits of using this approach:

- Simple to **add** new plugin specs. Just create a new file in your plugins module.
- Allows for **caching** of all your plugin specs. This becomes important if you have a lot of smaller plugin specs.
- Spec changes will automatically be **reloaded** when they're updated, so the `:Lazy` UI is always up to date.

Example:

- `~/.config/nvim/init.lua`

```lua
require("lazy").setup("plugins")
```

- `~/.config/nvim/lua/plugins.lua` or `~/.config/nvim/lua/plugins/init.lua` **_(this file is optional)_**

```lua
return {
  "folke/neodev.nvim",
  "folke/which-key.nvim",
  { "folke/neoconf.nvim", cmd = "Neoconf" },
}
```

- Any lua file in `~/.config/nvim/lua/plugins/*.lua` will be automatically merged in the main plugin spec

For a real-life example, you can check [LazyVim](https://github.com/LazyVim/LazyVim) and more specifically:

- [lazyvim.plugins](https://github.com/LazyVim/LazyVim/tree/main/lua/lazyvim/plugins) contains all the plugin specs that will be loaded

### ↩️ Importing Specs, `config` & `opts`

As part of a spec, you can add `import` statements to import additional plugin modules.
Both of the `setup()` calls are equivalent:

```lua
require("lazy").setup("plugins")

-- Same as:
require("lazy").setup({{import = "plugins"}})
```

To import multiple modules from a plugin, add additional specs for each import.
For example, to import LazyVim core plugins and an optional plugin:

```lua
require("lazy").setup({
  spec = {
    { "LazyVim/LazyVim", import = "lazyvim.plugins" },
    { import = "lazyvim.plugins.extras.coding.copilot" },
  }
})
```

When you import specs, you can override them by simply adding a spec for the same plugin to your local
specs, adding any keys you want to override / merge.

`opts`, `dependencies`, `cmd`, `event`, `ft` and `keys` are always merged with the parent spec.
Any other property will override the property from the parent spec.

## 📦 Migration Guide

### [packer.nvim](https://github.com/wbthomason/packer.nvim)

- `setup` ➡️ `init`
- `requires` ➡️ `dependencies`
- `as` ➡️ `name`
- `opt` ➡️ `lazy`
- `run` ➡️ `build`
- `lock` ➡️ `pin`
- `disable=true` ➡️ `enabled = false`
- `tag='*'` ➡️ `version="*"`
- `after` ℹ️ **_not needed_** for most use-cases. Use `dependencies` otherwise.
- `wants` ℹ️ **_not needed_** for most use-cases. Use `dependencies` otherwise.
- `config` don't support string type, use `fun(LazyPlugin)` instead.
- `module` is auto-loaded. No need to specify
- `keys` spec is [different](#%EF%B8%8F-lazy-key-mappings)
- `rtp` can be accomplished with:

```lua
config = function(plugin)
    vim.opt.rtp:append(plugin.dir .. "/custom-rtp")
end
```

With packer `wants`, `requires` and `after` can be used to manage dependencies.
With lazy, this isn't needed for most of the Lua dependencies. They can be installed just like normal plugins
(even with `lazy=true`) and will be loaded when other plugins need them.
The `dependencies` key can be used to group those required plugins with the one that requires them.
The plugins which are added as `dependencies` will always be lazy-loaded and loaded when the plugin is loaded.

### [paq-nvim](https://github.com/savq/paq-nvim)

- `as` ➡️ `name`
- `opt` ➡️ `lazy`
- `run` ➡️ `build`

## 📚 Plugin Authors

If your plugin needs a build step, you can create a file `build.lua` or `build/init.lua`
in the root of your repo. This file will be loaded when the plugin is installed or updated.

This makes it easier for users, so they no longer need to specify a `build` command.
